HAIR-BRUSH.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed July 24, 1920. Serial No. 398,626.

T 0 all whom it may concern Be it known that I, KATHERINE T. BARAL, acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have lnvented certain new and usefulImprovements in Halrmoved or separated from the back of the brush andsterilized or otherwise thoroughly cleansed, the brush dlfferlng llltllls respect from the ordinary brush 1n which the bristles are set intothe back, and which cannot be subjected to sterilization or to treatmentwith chemicals or otherwise for the purpose of cleaning it, especiallywhere the back and handle are of'wood, celluloid, or some other materialwhich would be liable to be affected either by heat or by the action ofany chemical substances employed for the purpose stated.

Another object of the invention is to provide, in a brush having a headwhich is separable from the back, a novel sectional construction of headsuch that when the head is removed fromthe back and the sections thereofare separated, access may be readily had to all portions of the tufts ofbristles for the purpose of freeing them from accumulations of foreignmatter and otherwise thoroughly cleansing them.

With regard to the head construction, the invention contemplates fomingthe said head in sections having spaced members which extendsubstantially in parallelism with relation to each other and which carrythe tufts of bristles, these members interdigitating when the sectionsare assembled so as to provide a'substantially solid head or backing forthe bristles and, on the other hand, when the sections are separated,presenting the bristles for cleaning in relatively widely spaced rows sothat the cleansing ofthe bristles'may be more readily and erfectuallyaccomplished.

' In the accompanying drawings:

Figure 1 is a perspective view of the brush embodying the presentinvention, the

bristle carrying head being illustrated as being separated from the backof the brush; Fig.2 is a vertical longitudinal sectional view throughthe brush with the parts thereof assembled;

F ig, 3 is a plan view of the bristle carrying head, the sectionsthereof being assembled and the bristle tufts being shown 7 in sectionso as to more clearly illustrate the construction of the said head;

Fig. d is a View similar to Fig. 3 but illustrating the sections of thehead separated; Fig. 5vis a vertical transverse sectional view throughthe brush;

Fig. 6 is a detail vertical longitudinal sectional View through aportion of the brush illustrating the means provided for holding thebristle carrying head assembled with the back.

Generally speaking, the brush comprises a back which is indicated ingeneral by the numeral 1 and whlch 15 provided with ahandle indicated ingeneral by the numeral 2 and further comprises a bristle carrying head 3and provided with tufts of bristles indicated by the numeral l. The back1 and handle 2 may be made of any desired material and ornamented orembellished in any desired manner, and inasmuch as these parts of thebrush will not be necessarily subjected to any injurious degree of heator to the action of cleansing preparations which may be employed intreating the bristles of the brush, these said parts may be made ofcelluloid, wood, metal, or any of the other materials usually employedfor the purpose or even of materials which have not yet heretofore beenemployed because of liability to deterioration or injury through theaction of heat or chemicals. On the other hand the bristle carrying head3 preferably has its sections made of metal or some other material whichwill withstand a sterilizing degree of temperature and the action ofcleansing compositions.

The bristle carrying head 3 comprises two sections which are nearly ofcounterpart preferably integral bristle carrying members 9 which in thepresent instance extend parallel to each other and which are spacedapart a distance substantially equal to their Width. To all intents andpurposes the terminal portions 8 maybe considered as end ones of theseries'of members 9 which project from the side portions 7 of the member5 inasmuch as these portions 8 are parallel The members 9 of the twosections 5 and 6 are alternately arranged or spaced so that when thesections areassembled, the members 9 thereof will become interdigitatedthus forming a substantially solid head carrying the bristles. When thesections are as sembled in the manner stated, the extremities of themembers 9 of each section will engage the inner edge of the sideportions 7 of the other section, and in order that the two sections maybe held against-relative displacement, the said extremities of all ofthe members 9 are preferably beveled as indicated by the numeral 10, andthe side inner edges of the side members 7 are undercut or beveled, asat 11, at points between the inner ends of the respective members 9 sothat the beveled portions will interlock as clearly shown in Fig. 5 ofthe drawings with the result stated.

When the sections 5 and 6 of the bristle carrying head are assembled,the outer edges of the side members and the outer edges of the terminalportions 8 will extend along an u'nbroken'outli'ne defining the margmalcontour of the bristle carrying head.

Thus with the sections assembled, the headmay. be disposed to fit snuglywithin a recess 12 which is formed in the under side of the back 1 ofthe brush and which is of a correspondmg contour, and this recess isformed in the forward portion of its wall with asocket 13 designed toreceive the projecting stud 14: formed upon one of the terminal portions8 of the section 5 of the bristle carryinghead. The other terminalportion of this section of the head is formed with a socket15 into whichis projected the engaging end 16 of a latch 17 which is slidably mountedin a bore 18 formed in the shank of thehandle 2. A

spring 19 is housed within an enlarged portion of this bore and bears atone end against a head 20 formed upon the inner end of the latch 17 andat its other end bears against .into or across the bore.

any suitable stop element 22 which projects An actuating button orfinger piece 23 is provided at the rear end-of the handle, and a'connecting element 24: is connected in any suitable manner to'the latch17 and extends through the bore'18 and is connected to the said buttonor finger piece 23. Thus when the button or finger piece is grasped andpulled re'arwardly, the latch 17 will be retracted, and the bristlecarrying head of the brush may bedisposed within the'reces's 12 intheback 1, or it may be removed from this recess if already in placetherein. On the other hand when the finger piece 23 is released thespring 19 will projectthelatch so as to cause the engaging end thereofto seat in the socket 15'and this together with the engagement of thestud 14 1n the socket 13 will serve to securely hold the bristle:carrying head connected with the back.

Returning again to a, consideration of Fig, 4 of the drawings whichillustrates the sections of the bristle carrying head relativelyseparated, it will be evident that inasmuch as the-bristle carryingmembers 9 are relatively widely spaced, and the bristle tufts arecarried upon these members in rows, the rows of bristles upon eachsection of the head, when the sections are separated,

will be likewise somewhat spacedfso that. as a result access may bemorereadily had to the bristles and they may be more thoroughly cleansed.Thus when the sections comprising the bristle carrying head of the brushare relatively separated, their separation results, in efi'ect,in arelatively wide spacing of the bristle-tufts so thatthe cleaning of thebristles may be more'readily effected. g V
